26 | # The goal of this test is to verify that support for the R_AARCH64_NONE | |
27 | # relocation is implemented and it can be used to inform a linker that | |
28 | # a section should be preserved during garbage collecting. | |
29 | # File aarch64_reloc_none.s describes two similar sections, .foo and .bar, | |
30 | # but .foo is referenced from .text using R_AARCH64_NONE against symbol foo. | |
31 | # When flag --gc-sections is used, .foo and its symbol foo have to be | |
32 | # preserved, whereas .bar and its symbol bar have to be discarded. | |
